The genus Bandavirus, belonging to family Phenuiviridae, order Bunyavirales, consists of eight tick-borne bunyaviruses. The Dabie bandavirus, formerly known as severe fever with thrombocytopenia virus (SFTSV), belongs to the genus Bandavirus. This emerging pathogen was first identified in central China in 2009. In recent years, the disease has been reported to cause several outbreaks in eastern Asia areas, including China, Japan, Korea, and Vietnam. Tick-to-human transmission is the main route of infection in humans, and transmission via the contact of body fluids from person-to-person was also reported. Despite its high fatality rate, there is currently no vaccine or antiviral therapy available. The therapeutic efficacies of several antiviral agents against Dabie bandavirus are still being evaluated. However, the virus is a potent pathogen with high biosafety experimental conditions. Therefore, replication-incompetent pseudotyped viruses play an important role. In this chapter, we succinctly summarize the basic features concerning Dabie bandavirus, including virion structure, genome characteristics, especially the characteristics of glycoprotein, and probable pathogenic mechanism. And, we put an important part in expounding the construction of pseudoviruses and its application.
布尼亚病毒科中的班纳病毒属包含 8 种蜱传布尼亚病毒。大别山病毒(前称发热伴血小板减少综合征病毒,SFTSV)属于班纳病毒属。这种新发病原体于 2009 年在中国中部首次被发现。近年来,该疾病已在中国、日本、韩国和越南等东亚地区多次暴发。蜱传感染是人类感染的主要途径,也有报告称通过人与人之间体液接触传播。尽管该病死亡率高,但目前尚无疫苗或抗病毒疗法。目前正在评估几种抗病毒药物对大别山病毒的治疗效果。然而,该病毒是一种具有高生物安全实验条件的烈性病原体。因此,复制缺陷型假型病毒发挥着重要作用。在这一章中,我们简要总结了大别山病毒的基本特征,包括病毒粒子结构、基因组特征,特别是糖蛋白的特征,以及可能的发病机制。我们还重点阐述了假型病毒的构建及其应用。
